Our review
ChatGPT is the closest thing to a universal AI assistant you can buy today. In our tests it drafted client emails, summarized a 40-page contract, and brainstormed a month of content ideas — all in one afternoon. Its main weakness is that it never flags its own uncertainty, so you have to build a habit of double-checking anything that matters.
